This is a way to grasp the enormity of the universe, and specifically how small a fraction of the sky the 'Hubble Ultra Deep Field' picture occupies. The Ultra Deep Field spans 2.4 arc-minutes in width (0.04 degrees), which means it's an incredibly tiny slice of the celestial canvas. In reality, you'd need approximately thirteen million exposures identical to this one to cover the entire expanse of the sky.
